Unzip folder to a directory of choice.
It is recommended not to use a directory that requires admin write permissions.
If you choose such, you will need to launch the utility as admin when ever you change settings.

To registers the application for the first time, run register.bat.

This will setup all nesseary registry entries to handle the callto links
If you ever move the folder, run this again to update the paths.

After running register.bat, Yealink Dialer should open it self.
When launching the application without a callto link, it will present the config interface.

Change these settings to reflect the correct settings of your Yealink device.

PHONEIP Specify the IP of the YeaLink Phone that the calls should be dialed with.
SIPACCOUNT Specify the SIP account the call should be made with. The format is USERNAME@SIPSERVERIP
USERNAME The username used to login to your Yealink phone's web interface.
PASSWORD The password used to login to your Yealink phone's web interface.

You can now hit save.

For this utility to work, you need to configure the Action URI Allow IP List

You can either specify your PC IP and limit it to just you, or use a wildcards in the IP field.

After this step is done, you can hit the test button.
It will ask you to confirm the test and will try to make a call to 012345767890 once you do.
The first time you do this, or when ever you change these settings, your Yealink Phone will ask you for permission.
Look at your phones screen and confirm that you want to allow remote access.

If you do not see any message on your Yealink Device, and it does not dial anything, check your settings again.

If everything is setup correctly, you should now be able to click on callto: and tel: links and it should open up Yealink Dialer.

In the data folder, you can find a config.ini with some additional options.

autoclose=true The dial window will auto close after a set time.
closedelay=8 Specifies the delay after which to auto close.
autodial=false Setting this to true will automatically try to call any number you click.
